Seedbed for growing vegetation
An artificial seedbed used in growing vegetation. The artificial seedbed comprises a base layer formed of a biodegradable product having a porosity and wet density that permit a root of the desired vegetation to penetrate the base layer and establish the vegetation for growing. The artificial seedbed also comprises an intermediate layer comprising a plurality of seeds for use in growing the desired vegetation. A cover layer cooperates with the base layer to form an envelope about the intermediate layer. The cover layer can be coextensive with the base layer and secured to the base layer by a bonding agent. The cover layer is formed of the same or different biodegradable product as the base layer. The material used in the cover layer permits the sprouting vegetation to penetrate it during the growing process.
